ESP32 is highly-integrated with in-built antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules. ESP32 adds priceless functionality and versatility to your applications with minimal Printed Circuit Board (PCB) area requirements.
DFRobot FireBeetle esp32 series is the low-power consumption micro-controller intentionally designed for Internet of Things (IoT) projects. FireBeetle Board - ESP32 integrates a Dual-Core ESP-WROOM-32 module, which supports MCU and Wi-Fi &Bluetooth dual-mode communication. The electric current is just 10μA in the deep-sleep mode. The main controller supports two power supply methods: USB and 3.7V external lithium battery. And both USB and external DC can charge the Lipo battery directly.
FireBeetle Board-ESP32 has made a special hardware design for Arduino IDE. You can make a download without switching booth-mode manually. It supports Arduino, IDF (linux), micropython etc. Moreover, FireBeetle made a pin mapping for Arduino IDE. It can be configured with Dx transport, compatible with UNO and reduce the entry barrier.
Now let's see some Firebeetle ESP32 Board Projects.
The small size and high performance makes FireBeetle become idea solution for IOT low power consumption projects.
Like what we heard in the song The Color of The Night, we always indulged in the psychedelic lights at night. The colorful lights tell sadness or happiness. I like the color of lights but I hate the uncomfortable manually switch of them. Fortunately, I have DIY a smart colorful light which satisfied my requirements of switch, color and even feelings.
I used to perform well at many sports: walking, running, riding bicycle, playing badminton etc. I love riding to travel around before long. Well, look at my portly belly…….. Well, anyway, I decide to restart to exercise. What equipment should I prepare? Besides sports facility, yes! I need an instrument! I believe with it, I can keep appropriate amount of exercise. Here the instrument comes into being. Let’s begin with a video!
Yes! What you have seen is a smart plugboard that converted by ESP32 master board and controlled by BLE of ESP32. As a fan of Arduino, I am worried about that ESP32 has been supporting Wi-Fi and Bluetooth but without libraries files for Arduino. However, the smart plugboard can control many slave equipment at the same time. Trust me, I have made two and tested them.
What a hot day it is! Too hot to drive and ride and I am thinking of making a temperature measurement sensor. With FireBeetle ESP32 produced by DFRobot and MLX90614 (a noncontact IR temperature sensor) on hand, let’s do it!
Have you ever been in a awkward situation where you’ve been in a office for a long time, but your colleagues just can’t remember your name clearly. Now there is a marvelous name badge for you to solve that problem. This badge is made of tricolor E-ink display designed by DFRobot. You can DIY own style for the name badge and add your unique idea into it. Just like this!
